Struct Header 

pub struct Header {
    pub version: u16,
    pub type_name: TypeName,
    pub device_name: DeviceName,
    pub timestamp: Timestamp,
    pub body_size: u64,
    pub crc: u64,
}

OpenIGTLink message header (58 bytes fixed size)

Header Structure (all numerical values in big-endian)

• Version: u16 (2 bytes)
• Type: char[12] (12 bytes, null-padded)
• Device Name: char[20] (20 bytes, null-padded)
• Timestamp: u64 (8 bytes) - high 32 bits: seconds, low 32 bits: fraction
• Body Size: u64 (8 bytes)
• CRC: u64 (8 bytes)

Fields

version: u16

Protocol version number (2 for version 2 and 3)

type_name: TypeName

Message type name

device_name: DeviceName

Unique device name

timestamp: Timestamp

High-precision timestamp (nanosecond resolution)

body_size: u64

Size of the body in bytes

crc: u64

64-bit CRC for body data

Implementations

impl Header

pub const SIZE: usize = 58usize

Header size in bytes

pub fn decode(buf: &[u8]) -> Result<Self>

Decode a header from a byte slice

Arguments

• buf - Byte slice containing at least 58 bytes

Returns

Decoded header or error if buffer is too short

pub fn encode(&self) -> Vec<u8>

Encode the header into a byte vector

Returns

58-byte vector containing the encoded header

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
